When and Where are Air Intake Screens used?

Air Handling Units (AHUs) & intake louvres

Air handling units have perishable internal filtration systems for delivering good, clean air to a building’s occupants.

As airborne debris is drawn through the AHU onto the heating/frost coil, pre-filter media, panel filters or bag filters, the air pressure drops and the fan motor is required to work harder in order to achieve the correct airflow.

Streme Air Intake Screens prevent pollen, leaves, insects and debris from being drawn into the system at the outset. Any build-up of debris can be quickly removed using a soft brush, garden hose or vacuum cleaner, significantly reducing maintenance time whilst protecting internal coils and filters.

Key benefits for AHUs

• Reduces energy consumption
• Significantly extends life of internal filters and ensures optimum filter efficiency
• Prevents clogging of coils, dampers and actuators
• Prevents efficiency drop caused by clogging
• Helps to improve indoor air quality
• Reduces maintenance by up to 75%
• Extends plant and component life

Chillers & dry air coolers

Chillers and dry air coolers generally have no means of protection from airborne debris. Cleaning the condenser coils is an extremely labour intensive process which often causes damage to the delicate fins.

A Streme Air Intake Screen significantly reduces maintenance time and reduces risk of breakdowns, all by preventing the airborne debris from fouling the coils.

Key benefits for chillers & dry air coolers

• Prevents clogging of condenser coils – This allows equipment to achieve set temperature points faster, reducing equipment running times and saving energy
• Reduce coil treatment and cleaning costs
• Prevent damage caused by power washing or the use of harsh/abrasive treatment chemicals
• Reduces maintenance time by up to 75%
• Prevents efficiency drops caused by clogging
• Eliminates downtime and lost productivity due to fouling & clogging
• Extends serviceable plant life

Cooling towers

A cooling tower draws in extremely large volumes of air in order to achieve its requisite cooling. Without filtration, pollen, leaves, insects and refuse can be drawn into the system, clogging fill and strainer components and increasing the microbiological load.

The greater the volume of the debris within the system, the greater the water treatment chemical requirement to counteract the biological loading and the more maintenance time is required in order to remove sludge build-up.

Key benefits for cooling towers:

• Prevents clogging of fill material for optimal heat rejection (extends fill life)
• Prevents sludge build-up in water basins
• Prevents clogging of strainers and blow-down valves
• Prevents clogging of heat exchangers
• Helps prevent bacterial proliferation by reducing the bio-loads that provide nutrients for bacterial growth, which increases water treatment chemical effectiveness
• Diffuses sunlight to help restrict algae growth
• Reduces maintenance by up to 75%
• Eliminates downtime and lost productivity due to fouling & clogging
